In a stand mixer bowl add bread flour, instant yeast, salt, and baking powder. Mix with the paddle attachment on the stand mixer.
2½ cups gluten free bread flour, 1¼ tsp instant yeast, 1½ tsp sea salt, 1/2 tsp baking powder
Run the mixer on low, then add the water, milk, egg, and melted butter. Increase the speed to medium for 2-3 minutes.
2/3 cup water at room temperature, 1/2 cup milk of your choice, 1 egg, 3 tbsp butter
Using a spatula to scrape the sides of the bowl, then cover with a plastic wrap. Refrigerate for 30 minutes.
While the dough is firming up, add basil, pine nuts lemon juice, garlic, salt, and pepper in a food processor. Process until finely chopped, then while it's running, drizzle olive oil until a thick paste is formed. Set aside.
2 cups basil, 1/3 cup toasted pine nuts, 2 tbsp lemon juice, 1 garlic clove, 1 tsp sea salt, 1/4 tsp ground black pepper, 1/4 cup grated parmesan, 1/4 cup olive oil
Place a parchment paper down, then place the dough on toe. Dust flour on a rolling pin, then roll the dough into a rectangle about 9x15 inches.
Spread the pesto on top evenly.
Roll the dough into a log from the long side, using the parchment on the bottom to help lift the dough.
Cut the log in half lengthwise so you see strips of pesto on the cut side.
With the cut side facing up, twist the two halves together so it's a long twisted log.
Connect the two ends together to create a wreath. Transfer to a baking dish along with the parchment paper. Cover with a plastic wrap and let this rise for 45 minutes. Preheat the oven to 350 degrees F.
Remove the plastic wrap, brush the top with egg wash, then bake for 35-40 minutes until golden brown. Enjoy warm, drizzled with or dipped in olive oil, salt, and/or parmesan.
